Actually Ethiopia deserves more than one trip, Tina, since there are many different regions.
These shots, as well as the header one, are from the “lunar” region of Danakil in the north-east; on the south is the Omo river basin with some really interesting ethnic groups (Mursi, Karo, Hamer, …); on the north is the Tigrai region with Lalibela and the rock-hewn churches. Not to mention the Simien mountains. I’ve only been to the first two destinations, but the others are on “the list” 😉
